Application filed trul 9,'1925,'Seria1 No: 42,474. Renewed April 27,1927.

This invention relates to an improved device whereby oil may be lifted from a well without the aid of a pump after the oil has stopped flowing from the natural cause.

The invention has more particular reference to an arrangement of details whereby compressed gas may be introduced into the oil well tubing to lift the column of oil to the surface by pressure from the shaft.

The details and their relative arrangement, which serve to form an advantageous and practical structure will become apparent from the following detailed description and will be pointed out specifically in the appended claims.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a central vertical section througha device constructed in accordance with the present invention.

Fig. 2 is a cross section, on an enlarged scale, taken upon the plane of the line 2-2 of Fig. 1, looking downwardly.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1 looking upwardly.

Referring to the drawings in detail, the reference character 1 designates the usual outer casing of an oil well and 2 designates the tubing confined therein. In the present instance the tubing embodies a relatively enlarged' portion 3 joined to the restricted portions through the medium of reducing necirs 4. Arranged within this relatively enlarged portion is a compressed gas conducting pipe the intake of which is indicated at 5. This pipe comprises a depending portion 6 ex tending downwardly in spaced parallelism to the wall'of the tubing, an upstanding branch 7 terminating at a predetermined point, and an elbow or bight portion 8. Thus, a substantially U-shaped pipe having branches of unequal length is provided for introducing the compressed gas into the tubing. Above the intake 5 is a baffle plate 9 having an eccentrically located hole or passage from which a relatively larger pipe 10 depends. This pipe .10 depends down to a point terminating adjacent the elbow 8 of the U-shaped gas pipe. In fact aportion rests upon the top of the elbow. Obviously, this pipe 10 serves to confine'the upwardly lifted oil column and with the arrangement specified wherein the branch 7eXtends' above the intake end of the pipe 10, the oil is caused face in a well known manner. careful consideratlon of the description in I claim as new 'is:

to enter the pipe with greater velocity under a degree of suction produced.

The gas pipe is welded or otherwise supported from the tubing 3, while the part 10 is connected to the tubing through the medium of radial webs 11. Although I have not shown it, it is understood that the usual standing ball check valve may be located at the bottom of the well and that an. appropriate packer may be interposed between the tubing and well casing to prevent the gas from goingdown into the well and agitating up the sand to interfere with the proper flow of the oil from the bed.

It will be noted that at the upper end of the tubing 10 which terminates in the trans verse plate 9, that an enlargedchamber is provided in the upper end of the enlarged portion 3 of the pipe section which aids the nozzle 7 for the gas discharge to thoroughly commingle the upwardly flowing gas with the oil for accelerating the upward flow of oil in the pipe 2 by the aerating action of the gas inaddition to the upward force due branches 6 and 7, thus acting on the oil column in. the pipe 10 and lifting it to the sur- No doubt, a

connection with the drawings will enable persons skilled in the art to which the in vention relates to obtain a clear understand ing of the same. Therefore a more lengthy description is thought unnecessary;

While I have shown and described the preferred embodiment of the invention it is to V be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what A flowing device for oil wells, comprising a pipe section having a portion of enlarged diameter, reducing necks connecting the portions of enlarged diameter with the pipe section, a transverse plate mounted in said enlarged portion inspaced relation below the upper neck, a tubular member mounted eccentrically insaid transverse plate and extending through the enlarged portion and providing an oil passage through said enlarged portion, and a discharge nozzle having one end extending upwardly within the tubular member in concentric relation and discharging upwardly therein, and the opposite end mounted in the enlarged portion of said pipe member, and communicating with the exterior thereof, said pipe section and enlarged portion being adapted for mounting in a well casing wherein the well casing is adapted to conduct gas under pressure outwardly of said pipe section for discharge through the nozzle, the transverse plate member forming an enlarged chamber above l/V ILB UR R.
